Porticus Hadriani 1


architectural promenade

...the new ideas re: the architectural promenade that developed because of the Danteum. Essentially, the Danteum has the same sequential series of architectural "events" as the formula for the architectural promenade that I have extracted from Le Corbusier and Stirling. The Danteum, however, adds the element of a journey from the profane to the sacred, and this addition significantly opens up the interpretive field and the buildings that can now be included as exhibiting the architectural promenade formula.

With regard to the profane/scared aspect, the triumphal way within Piranesi's Campo Marzio exhibits the same sequence. The procession (promenade) begins at the Templum Jani, a tetrahedron, which is the forest, the pilotis that raise the box. From there the route jaggedly marches through the "theater district" (downtown)--this is hell, the profane, the lower level. Just as the "way" approaches the Banks of the Tiber for the first time, the procession becomes straight and passes repetitive / monotonous buildings. The way remains perfectly straight except for two 90 degree turns, and this course comprises the greatest length of the promenade. (The straight portion of the procession passes, in sequential order, the Hecatonstylon and the outer niched wall of the Horti prius Pompejani deim Marci Antonii; then the long portico of the Stadium opposite the Domus Alexandri Severi; and across the river between the Porticus Hadriani and the Sepulchrum Libertorum et Servorum of the Bustum Hadriani. These buildings well exemplify the notion of inside/outside, thus tying the triumphal way more closely to the architectural promenade formula.) In the course of this long march, the procession crosses over from the area (of the Campo Marzio) that primarily represents life (inside/outside -- osmosis connection?) into the area that is primarily of death (the Bustum Hadriani). This is the same transition as in the Danteum's Purgatory, and the middle inside/outside level of the Villa Savoye (etc.). Ultimately, the Triumphal way ends at the Templum Martis, easily the most sacred place/space of the Campo Marzio. This culmination to the triumphal procession is analogous to the Paradiso of the Danteum, and to the solarium of the Villa Savoye (etc.). Of course, this has major implications towards my previous analysis of the Triumphal Way.

Porticus
1998.12.01

The porticus is the most prevalent building typology within the Ichnographia Campus Martius. At least one porticus is found within every quadrant of the large plan, and cumulatively they add up as the most numerous building type within the Campus Martius, a portrayal which is both historically and archeologically sound. That is not to say, however, that each porticus Piranesi delineates has a historical basis. For example, the two Porticus Hadriani, the Porticus Horti Domitiae, at least one of the Porticus Neronianae, the Porticus praebentes umbraculum diei ab aesti, the Porticus Quirini, and the Porticus Trajani have no relationship with historical fact. Furthermore, many of those porticus that hold factual veracity, Piranesi dislocates within the large plan, and, overall, none of the porticus within the Ichnographia, with the exception of the Porticus Septorum Juliorum, express historically correct designs.

Even though Piranesi employs a different imaginative arrangement for each porticus delineated within the Ichnographia, he nonetheless exhibits an overall consistency within a discernible set of design patterns. Each porticus contains a profusion of colonnades. The oldest porticus are simply linear in plan, and those along major axes such as the Via Lati and the Equiria are linear in the extreme. The Porticus Horti Domitiae and the Porticus Europae incorporate circular motifs, and the two Porticus Neronianae are cruciform in plan. Finally, the porticus of Hadrian and the later emperors are very hybrid in that they incorporate any number of colonnade plan motifs, as well as contain an array of enclosed spaces.
